Justin T. Gibbs df8f908079 Restore queue depth settings across tag disable events. The system often 
disables tag queuing temporarily in order to allow controllers a window
to safely perform transfer negotiation with non-compliant devices.  Before
this change, CAM would restore the queue depth to the controller specified
maximum or device quirk level rather than any depth determined by reactions
to QUEUE FULL/BUSY events or an explicit user setting.

During device probe, initialize the flags field for XPT_SCAN_BUS.
The uninitialized value often confused CAM into not bothering to
issue an AC_FOUND_DEVICE async event for new devices.  The reason
this bug wasn't reported earlier is that CAM manually announces
devices after the initial system bus scans.
